4. Open the lower pressure side of the manifold valve assembly and start the vacuum pump.The switch at the high pressure side of the manifold valve assembly should be kept closed,or evacuation does not fail.

5. Operate vacuum pump until a vacuum of 500 microns or less is achieved. The evacuationduration depends on the vacuum pump size and unit’s capacity, generally 20 minutes for the9,000 BtuH units, to 1 hour for a larger 36,000 BtuH unit.

6. Close the manifold valves and shut off the pump.

a. If vacuum holds below 700 microns for 15 minutes, the system can be considered dry and leak free. Go to step 5.

b. If vacuum increases to 800 microns or greater, this is an indication of moisture in system or a leak exist. Identify leak and repair as necessary, after which repeat steps 4 and 5. If moisture is suspect, purge system use triple evacuation method using dry nitrogen.

TESTING AND INSPECTION

Leaking Test

1. Connect the charging hose of the manifold valve to charge the end of the low-pressure valve.2. Add dry nitrogen to a pressure of 200 lbs. Tightly close both high- and low-pressure valves.3. Leak-test flare fittings with soap bubbles. If no leak is detected, release nitrogen.

CAUTIONUse vacuum pump, rather than refrigerant, to discharge air when installing the unit.

Additional Charge

The outdoor unit contains enough refrigerant charge for up to 25 feet (7.5 m) from the factory. When the piping is greater than 25 feet (7.5 m), but not to exceed the maximum piping length as stated in the System Requirement section, additional refrigerant charge is necessary. For the additional amount, see the table below.

Unit Size Add’l Refrigerant Amount for Extra Pipe

9,000 -18,000 0.2 oz/ft (20 g/m)24,000 - 36,000 0.54 oz/ft (50 g/m)

Vacuum Procedure (con’t)

7. Confirm that manifold valves are closed and disconnect the vacuum pump.

8. Open the service valves to the fully ‘back-seat’ position to let the refrigerant flow to the indoor unit and balance the pressure in system.

Important: Do not allow air to enter the connection pipe when removing the hose.

9. Replace service valve caps and tighten.

TROUBLESHOOTING

PROBLEM

System does not restart.

Indoor unit emits unpleasant odorwhen started

You hear a“water flowing”sound.

A thin fog or vapor coming out of the indoor unit when system isrunning.

You hear a slight cracking soundwhen the system stops or starts.

The system will not run.

Water leaking from the indoor unit into the room.

CAUSE/SOLUTION

Cause: The system has a built-in three-minute delay to prevent short and/or rapidcycling of the compressor.

Solution: Wait three minutes for the protection delay to expire.

Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil surfaces or the air filter.

Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist,contact a qualified service professional to clean the coil surfaces.

Cause: It is normal for the system to make“water flowing”or“gurgling”soundsfrom refrigerant pressures equalizing when the compressor starts and stops

Solution: The noises should discontinue as the refrigerant system equalizes aftertwo or three minutes.

Cause: It is normal for the system to emit a slight fog or water vapor when cooling extremely humid warm air.

Solution: The fog or water vapor will disappear as the system cools and dehumidifies the room space.

Cause: It is normal for the system to make “slight cracking” sounds from parts expanding and contracting during system starts and stops.

Solution: The noises will discontinue as temperature equalizes after 2 or 3 minutes.

Cause: There are a number of situations that will prevent the system from running.

Solution: Check for the following:• Circuit breaker is “tripped” or “turned off.”• Power button of remote is not turned on.• Batteries in the remote controller are low.• Remote controller is in sleep mode or timer mode.• Otherwise, contact a qualified service professional for assistance.

Cause: While it is normal for the system to generate condensate water in coolingmode, it is designed to drain this water via a condensate drain system to a safe loca-tion.

Solution: If water is leaking into the room, it may indicate one of the following.

• The indoor unit is not level right to left. Level indoor unit.

• The condensate drain pipe is restricted or plugged. All restrictions must be removed to allow continuous drainage by gravity.

• If problem persists, contact a qualified service professional for assistance.

TROUBLESHOOTING

PROBLEM

Water leakage from the outdoor unit.

The unit is not heating or coolingadequately.

Wireless remote controller does not work.

The unit will not deliver air.

Moisture or condensation on the discharge air louvers or outlet vents.

CAUSE/SOLUTION

Cause: It is normal for the outdoor unit to generate condensate water in the reverse cycle heating and defrost mode.

Solution: This is normal. No action is required.

Cause: There are a number of reasons for inadequate cooling or heating.

Solution: Check the following:• Remove obstructions blocking airflow into the room.• Clean dirty or blocked air filter that is restricting airflow into the system.• Seal around door or windows to prevent air infiltration into the room.• Relocate or remove heat sources from the room.

Cause: There are a number of possible reasons

Solution: Check the following:

• The batteries might be low. Change the batteries.

• The remote controller must be within 25 ft. (7.5 m) with no obstructions of the indoor unit. If remote controller needs to be replaced, contact a qualified service professional for assistance. In the meantime, use the Aux button to operate the system.

Cause: There are a number of system functions that will prevent air flow.

Solution: Check for the following:

• In heating mode, the indoor fan may not start for three minutes if the room temperature is very low. This is to prevent blowing cold air.

• In heat mode, if the outdoor temperature is low and humidity is high, the system may need to defrost for up to 10 minutes before beginning a heating cycle.

• In dry mode, the indoor fan may stop for up to three minutes during the compressor off delay.

• Otherwise, you should contact a qualified service professional for assistance.

Cause: It is normal for the system to develop condensation or moisture on the discharge air louvers when cooling warm humid air for a long period of time.

Solution: The condensation or moisture will disappear as the system cools and dehumidifies the room space.
